After the tuner is turned on, it is checked whether it is the guqin mode F tone, and must be switched to the guqin mode F mode.
It is not the guqin external F mode, nor the twelve temperament mode.
Press the switch button to view the mode, press the switch button continuously to switch modes.
Tuning is the twist on the back of the Guqin, not the knot on the top of the string.
Guqin 1-7 string tuner corresponds to letters and numbers: C1, D2, F3, G4, A5, C6, D7. 1 string is the thickest, 7 string is the finest.
